# OSSystemExtensionManager

A type that facilitates activation and deactivation of system extensions.

```
class OSSystemExtensionManager
```

## Overview

Create an instance of [`OSSystemExtensionRequest`](/documentation/SystemExtensions/OSSystemExtensionRequest) with the class methods on that type, and submit it to the shared instance of the extension manager with [`submitRequest(_:)`](/documentation/SystemExtensions/OSSystemExtensionManager/submitRequest(_:)). Set the [`delegate`](/documentation/SystemExtensions/OSSystemExtensionRequest/delegate) on the request to receive the result of the activation or deactivation. The delegate also receives notifications if the user needs to authorize the extension or if a version conflict occurs.
